Description
The utility model belongs to compressed air and purify to be equipped with, and relates in particular to the compressed air oil removing and removes the device of moisture content.
Air compressor disposes air cleaner and aftercooler usually, and the former sucks the contained most of grit of air in order to remove, and the latter is then in order to remove a part of moisture content and mist of oil.Adopting pocket type or self-cleaning air filter, and aftercooler outlet compressed air temperature is under 40 ℃ the condition, the compressed air of 0.5～1.0MPa in the dustiness of air accumulator outlet less than 0.1mg/m
3, moisture content is 40 ℃ of pressure leak sources, oil moisture content is 10～50mg/m
3Such quality can not satisfy most of users' requirement.
In order to improve compressed-air actuated quality, also need compressed air purifier to be installed according to user's requirement.This device has different patterns, and in the prior art, fairly perfect purifier is the mode that freezing type drier A connects with absorption type dryer B, and flow process as shown in Figure 1.Its purification process is as follows:
1, freezing type drier A is decreased to about about 2 ℃ of pressure leak source with 40 ℃ of compressed air water contents.
(1-1) in the forecooler 4 of freezing type drier A, the Wet Compression air is cooled to about 25 ℃ by about 40 ℃ and further removes moisture content and mist of oil.
(1-2) in the evaporimeter 7 of freezing type drier A, cooled dose of evaporative cooling of compressed air is cooled to about about 2 ℃ by about 25 ℃, further removes moisture content and mist of oil again.
(1-3) are sent about about 2 ℃ compressed air by evaporimeter 7 and are back to forecooler 4, and about 40 ℃ Wet Compression air heat exchange of sending in this and air accumulator rises to about 30 ℃ by about 2 ℃.
2, about 30 ℃ compressed air is delivered to efficient degreasing filter 8, oil moisture content is reduced to the content of customer requirements.For centrifugal or non-lubricated air compressor, can not establish the efficient degreasing filter.
3,30 ℃ compressed air reduces to moisture content in the compressed air content of customer requirements in absorption type dryer 12.Absorption type dryer has three kinds of alternating temperature regeneration and pressure swing regeneration and alternating temperature pressure swing regenerations.Alternating temperature regeneration is that surrounding air is regenerated to drier through being heated to more than 120 ℃ to send in the drier with blower fan, with cold air drier is cooled off after the regeneration again; Pressure swing regeneration be with dried compressed air through being decompressed to about 0.015MPa, enter drier drier regenerated, need to consume more compressed air; The alternating temperature pressure swing regeneration is that dried compressed air is decompressed to about 0.015MPa, after heater via is heated to about 70～80 ℃ again, sends into drying drier is regenerated, and needs to consume the small amount of compression air and need outside heat simultaneously.
The major defect of existing purification techniques has:
1, personal air supply is big.When adopting the pressure swing regeneration method, regeneration reaches about 15～20% of total compression air capacity with air supply; When adopting alternating temperature pressure swing regeneration method, it is about about 8% that air capacity can reduce to, but heater need be set, and present heater is not long service life.
2, energy consumption is big.The forecooler 4 of the dry stool A of freezing type adopts light pipe or fin-tube type heat exchanger, heat transfer coefficient is little, because the restriction of equipment volume, heat transfer area can not be excessive, therefore, general 40 ℃ of Wet Compression air only are cooled to about 25 ℃, and then enter evaporimeter 7 and be cooled to about about 2 ℃, and the wasted work of its refrigeration compressor is bigger.During the regeneration of adsorption dehumifier alternating temperature, heater capacity is big, has increased power consumption, and auxiliary equipment is many.
3, freezing type drier A, efficient degreasing filter 8 and absorption type dryer 12 are three separate equipment, and floor space is big, operation inconvenience.
The purpose of this utility model provides a kind of change gas flow process, reduces the operating temperature of absorption type dryer, to increase adsorbance, improves only than effect, also can reduce the combined compressed air purifier of regeneration with air supply simultaneously.
In order to achieve the above object, the utility model has adopted following design: the combined compressed air purifier, it comprises heat exchanger, precooler, evaporimeter, efficient degreasing filter and absorption type dryer.The low temperature side of a heat exchanger pipeline with pipeline and absorption type dryer rear portion is joined, the high temperature side of heat exchanger another pipeline with pipeline and absorption type dryer rear portion is joined, the low temperature side of a forecooler pipeline with pipeline and absorption type dryer rear portion is joined.
Adopt the utility model can reach following effect:
(1) owing to adopted plate-fin heat exchanger as forecooler, thereby can: a) reduce the outlet temperature of humid air,, be reduced to about 12 ℃, thereby reduce the power of refrigerator, save its power consumption by being generally at present about 25 ℃; B) obtain～a small amount of dried compressed air of about 38 ℃ is used for the regeneration of absorption type dryer; C) area and the volume of minimizing heat exchanger make device compact more.
(2) operating temperature of absorption type dryer is about 0.5～2 ℃, and prior art is 30 ℃, and therefore adsorbance of the present utility model is big, and the outlet air pressure leak source can reach-70 ℃, i.e. good purification.
(3) absorption type dryer adopts the regeneration of alternating temperature transformation method, can reduce regeneration and use air supply, and prior art is 15～20%, and the utility model is about about 4～8%, and does not need external heat source.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 has compressed air purifier now
Fig. 2 combined compressed air purifier
Compressed air behind air accumulator, enters this combined compressed air purifier again about aftercooler cools to 40 ℃.The low temperature side of heat exchanger 1 is connected with the pipeline 10 at absorption type dryer 12 rear portions with pipeline 3 and pipeline 9, and (pressure leak source-70 ℃) introducing heat exchanger 1 and the high temperature compressed air (40 ℃) that enters carry out heat exchange so that the compressed air that absorption type dryer is dried 2 ℃～5 ℃.Air after heat exchanger 1 heating is joined with the pipeline 11 of pipeline 2 with absorption type dryer 12 rear portions, so that heated air (35～38 ℃) is incorporated into absorption type dryer 12, its adsorbent is regenerated, cancel the air heater of prior art, reach the purpose of energy savings.With the low temperature side of precooler 4 with pipe 6 and manage 9 and join with the pipeline 10 at absorption type dryer 12 rear portions, so that dried Cryogenic air is introduced forecooler 4, compressed air about 40 ℃ is cooled to about 12 ℃, be warming up to about 30 ℃ through dry air after the heat exchange, draw through pipeline 5, use for the user.It is in order compressed air further to be cooled to about 2 ℃, to introduce efficient degreasing filter 8 again and filter, entering absorption type dryer 12 at last and carry out degree of depth adsorption dry processing that evaporimeter 7 is set.Two of absorption type dryer 12 operated by rotary motion, an absorption, another regeneration, two drier alternations.Owing to introduce the compressed air temperature lower (0.5～2 ℃) of absorption type dryer 12, so advantages of good adsorption effect can improve the compressed air quality.
When the utility model changes forecooler at a little, can obtain the compressed air of two kinds of qualities.
When the utility model is used for oil free screw, piston type or centrifugal air compressor, can not establish the efficient degreasing filter.
It is the industrial compressed-air actuated purification of 0.5～2.0MPa that the utility model can be used for pressure.
